Ok, I'm not the smartest guy...If the hatcheries are shut down on rivers where the wild runs are endangered, is that a good thing? Do they have that great an impact on the survival of "wild" fish? Seems like it's just nice to have a hatchery fish to keep..And how many years would it be until wild fish populations would be strong enough to handle intense fishing pressure? Seems like habitat loss and netting play a very large role in returns. Please forgive my ignorance, I'm still learning.
